Development, manufacture and testing of horizontal axis wind microturbines with power of 10 kw

Abstract

Under the circumstances of the total energetic recourses deficit in the Republic of Moldova appears the problem of non-traditional sources utilization recovered by energy. Important sources of renewable energy are the wind, solar and hydraulic energies. Wind energy is one of the most ancient forms of energy used by Homo sapiens. Concurrently with the emergence of new energy sources (fossil fuels, atomic energy etc.) this form of energy yielded up the priority and changed itself into alternative one, which, at present, begins to regain its positions not only from the ecological, but also from the economical point of view. Under the circumstances of the present energy crisis (even at worldwide level), the wind energy conversion systems could have a significant weight in the production of (mechanical, electrical etc.) energy in the Republic of Moldova, in particular, for providing the individual consumer with energy using wind turbines of low power (until 30kW). In order to redress the situation of the energy sector, the Government of the Republic of Moldova, through the agency of the Supreme Council for Science and Technological Development (Academy of Sciences of Moldova), initiated more State Programs, in which one of the directions is immediately related to the elaboration of renewable energy conversion systems. This paper deals with the elaboration and fabrication of the industrial prototypes of horizontal axis wind microturbines with power of 10 kW. Currently have been manufactured 10 horizontal axis wind turbine with power of 10 kW, concerning some novelty elements. These wind turbines will be installed in different geographic areas of the Republic and will be tested. Test results will be included in this paper.
